 Hello, welcome to NPTEL NOC, an introductory course on point sector power here, part two. I am Anand Arshastri, retired emeritus fellow from IIT Bombay Department of Mathematics. I have a team of teaching assistants here, Professor Ankum Tikken Singh from Nehru in Shillong, Professor Arjala and Bhopang also from Nehru Shillong, Oankar Javedkar from IIT Bombay and Sushil Singla from Shivanadar University. So, as name suggests, this is a part two of the point set topology course. Point set topology part one was also a NPTEL NOC course which was introduced in the last semester. You can have a look at the content page here, bibliography and content page chapter one on differential calculus on Banach spaces, then compactness and separation axioms, there are compactness and partition affinity, other notions of compactness, compactification, matrization, nets and filters and global separation axioms and then Huravi Swalman dimension theory and one more chapter named it is not shown here, unfortunately very important chapter manifolds. So, the point is that the second part naturally assumes that the participants of this course are fairly familiar with the content of part one. We actually do not assume that you have attended part one, you may have learnt that part on your own somewhere else from through books or some other course, but if you have attended part one lecture and have understood a good percentage of that material then sailing with this part two will be very easy for you. So, such people will benefit much better than people who have not attended part one. The course is delivered in 60 modules of approximately 30 minutes age just like many other NPTEL courses. We expect that learners will be able to cope up with 5 such modules per week that is like a 2 and half hours contact hour. An important aspect of mathematical studies is to keep up continuity. If you do leave something out somewhere in between it is most likely that you will have difficulty in understanding some later chapters, later portions. It can happen immediately also or it may happen little later also quite often it happens immediately. So, that is what mathematics is. So, the key here is keep the continuity, continuity of studies. In any case, you have your YouTube, you are free to use them in your own free time. So, that is the whole advantage of having these recorded lectures. In order to have the students in this respect, in this respect means what in keeping touch with the whole thing. We have a discussion portal in which all participants can raise their queries. Suppose you have not understood something despite having tried. You can try to get these difficulties squared by the team of this TAS. So, they are quite enthusiastic about teaching. They will be constantly looking at into these queries. The common portal is there for all of you to put your questions and then they will be responding to them also. The set of lecture notes for part one as well as for part two will be made available right in the beginning of the course. So, that will also help you to understand the material. Along with this, there are also a number of pre-planned live interactive sessions directly with me. With more enthusiasm from the participants from your side, additional interactive sessions can be arranged. That is courtesy NPTEL team of course. So, we hope to make this course a joyful learning experience. I once again welcome you to this course. Thank you.
